Can you pick it in 78 seconds?

You've reviewed the concepts and taken the mock exams. Then the real exam hands you a long scenario and two options that both sound defensible, while the clock keeps moving. That's not a knowledge gap. It's a decision skill, and most study material never trains it.

Five steps for when
two answers look right

The method from the free workbook. You'll use it in the test below.

1

Read the question line first

Know what you're hunting before you read the story.

2

Name the behavior

Whose behavior, doing what. Two or three words.

3

Mark what changed

Up or down. Added or removed. Anything that changed before it.

4

Use only what you're given

If an option needs an assumption, it's out.

5

Kill every wrong option with a reason

Can't name the reason? Go back to step 3.

10 scenarios. Exam format.
No hints until the end.
